Although the diagnosis is based primarily on microscopic features, patient stratification relies on clinical data such as proteinuria and etiological criteria. FSGS affects both children and adults and has an elevated risk of progression to end-stage renal disease. The prevalence of FSGS is rising among various populations, and the efficacy of various therapies is limited. Therefore, understanding the pathophysiology of FSGS and developing targeted therapies to address the complex needs of FSGS patients are topics of great interest that are currently being studied across various clinical trials.

Moreover, it has shed light on the pathways through which most anticancer therapeutics induce tumor cell death, including targeted therapy and immunotherapy. These mechanistic studies have paved the way for the development of therapeutics directly targeting either pro- or antiapoptotic proteins. Notably, the US Food and Drug Administration (FDA) approved the BCL-2 inhibitor venetoclax in 2016, with additional agents currently undergoing clinical trials. Recent research has brought to the forefront both the anti- and proinflammatory effects of individual apoptotic pathways.

Recent work has shed light on the importance of RNA damage, which triggers a host of conserved RNA quality control mechanisms. Because many RNA species are transient, and because of their ability to be retranscribed, RNA damage has largely been ignored. Yet, because of the connection between damaged RNA and DNA during transcription, and the association between essential complexes that process or decode RNAs, notably spliceosomes and ribosomes, the appropriate handling of damaged RNAs is critical for maintaining cellular homeostasis.

We consider emerging data that support the possibility of neuronal or immune dysfunction as primary drivers of MSA. These hypotheses are placed in the context of a major recent discovery that αSyn is conformationally distinct in MSA versus other synucleinopathies such as Parkinson's disease. We outline emerging techniques in epidemiology, genetics, and molecular pathology that will shed more light on this mysterious disease.

However, the disease mechanisms that promote germinal matrix hemorrhage remain unclear. Here, we review recent advances using single-cell transcriptomics to uncover novel mechanisms that govern neurogenesis and angiogenesis in the germinal matrix of the prenatal human brain. These approaches also reveal the critical role of immune-vascular interaction that promotes vascular morphogenesis in the germinal matrix and how proinflammatory factors from activated neutrophils and monocytes can disrupt this process, leading to hemorrhage.

Fetomaternal tolerance is not absolute, and unfortunately there exist several pregnancy complications that arise from breaks therein. Here, important historic and recent developments in the field of fetomaternal tolerance pertaining to maternal B cells and antibodies are reviewed. General rules from which to conceptualize humoral tolerance to the placenta and fetus are proposed.
